Three forces that are acting on each charges, see the figure below that is for the q on the rightside

We have rope tension (T), coulomb force (Fc) and the weight (W). These three forces are in equilibrium conditions. Get the distance between two charges (r) where r = 2d and d = l cos 53° see the figure:

r = 2 l cos 53°
r = 2 (25)(0.6) = 30 cm = 0.3 m

Apply the equlibrium conditions and get the components of tension rope (T) bring to x-y cartesian
